RTOS-32 is
not property of I.C.S., we are using this workbench as a base
platform.
I.C.S. GmbH: After years of successful work with
RTK-C and the PowerPack (32 Bit DPMI) from Borland we have decided to
port the EC32 system to a new platform. Our evaluations have shown
that RTOS-32 suits our ideas and requirements in the best way. This
does not mean, that EC-32 will be discontinued but RTC-32 will form a
parallel branch and improvements will be implemented in both packages.
We would like to thank Peter Petersen

for his outstanding support and help during the struggle for success.
On Time RTOS-32 offers a complete solution for high performance
embedded systems using x86 compatible CPUs. It is important to
understand how the various components (RTTarget-32, RTKernel-32,
RTFiles-32, RTPEG-32, and RTIP-32) of On Time RTOS-32 fit together as
parts of a scalable architecture.
RTTarget-32 is the foundation of On Time RTOS-32. It includes
all development tools required to run 32-bit applications on an
embedded system. RTTarget-32 can process a single 32-bit application
built with a Win32 compiler to run on the embedded target. It supplies
boot code to initialize the target's hardware and to subsequently
invoke the application automatically. RTTarget-32 also supplies an
extensible subset of the Win32 API, allowing it to run programs
developed for Windows NT/2000/XP in an embedded environment under
real-time conditions. RTTarget-32's Win32 emulation is comprehensive
enough to support the startup code and run-time systems of most Win32
compilers unmodified. Both source level and binary compatibility
between Windows NT and RTTarget-32 are possible. Many programs or
libraries and DLLs for Windows NT can be ported without or with only
minor changes to RTTarget-32. RTTarget-32 can be regarded as a very
small Windows NT kernel for embedded systems with a minimum memory
footprint of a mere 16k RAM/ROM.
Another advantage of RTTarget-32's Windows NT compatibility is its
support for NT development tools. You can develop programs using
Borland C++, Borland Delphi, or Microsoft Visual C++. The respective
compilers' command line tools as well as the IDEs such as Microsoft's
Visual Studio are supported. RTTarget-32's Win32 compatibility allows
its compiler support to be extended to any tool which generates
standard Win32 PE files (Window's executable file format).
RTKernel-32 is a real-time multitasking kernel for RTTarget-32.
It is a high-performance real-time scheduler supplied as a set of
linkable libraries which can extend the functionality available to
RTTarget-32 programs. It adds most Win32 thread API functions for
thread creation and management, semaphores, critical sections, etc.,
to RTTarget-32's Win32 emulation library. It also defines its own API
and functionality beyond the capabilities available under Windows NT
to meet the needs of real-time systems (e.g., deterministic scheduling,
priority inheritance, a comprehensive interrupt handling API,
debugging functions, etc.).
RTFiles-32 is the file I/O component of On Time RTOS-32. It
provides its functionality through the Win32 API emulation of
RTTarget-32, too. Therefore, all file I/O related functions of the
C/C++ or Pascal run-time system can be used. RTFiles-32 supports the
DOS/Windows FAT file system structure on floppy disks, IDE, and flash
disks and adds enhancements for real-time file I/O. Just like
RTKernel-32, RTFiles-32 must be used with RTTarget-32. RTFiles-32
supports RTKernel-32, but does not require it.
RTPEG-32
is an event-driven, object-oriented C++ GUI library for embedded
systems. It supports implementing professional Windows 95 or custom
look-and-feel user interfaces with mouse and keyboard support. Device
drivers for VGA and SVGA/VESA graphics hardware are included.
RTIP-32
is an add-on to provide networking capabilities for On Time RTOS-32.
It implements the core TCP/IP protocols for Ethernet and serial
communications. RTIP-32's functionality is provided to the application
using the Unix socket API and an extended native API. RTIP-32 requires
RTTarget-32 and RTKernel-32. A wide range of application-specific
add-ons are available for RTIP-32 (e.g., PPP, FTP, TFTP, Web Server,
SMTP/POP3, Telnet, SNMP, and DCHP). |
